Gideon Navs Long Sword

PSA: the design has some flaws that I found while sanding my print. I'll try to fix them ASAP and upload the new files. Sorry for this, I wasn't aware of these issues :/

This is my design for Long/Great Sword of Gideon Nav from Gideon the Ninth/the Locked Tomb series.
I am absolutely in love with this series and Gideon herself, so i decided to make a design for her sword. The thing is, the sword is canonically 6' or around 180cm tall, so that is (literally) a tall order to fill. The model should be to scale for that, so if you want to make it a reasonable size, you need to scale it down.
I'll try and update it as I make the model print ready and eventually print it as well. So far, it's only the full sword in one, with (hopefully, please check whether its properly installed) room for a 12mm, 160cm rod inside for stability. My last 3d printed sword when a single manga volume fell on it, so I'm a bit careful with this one.
I'll update it as I break the model down into printable a
